Stealing from rabbits

Whenever I feed my three rabbits, my sole hen likes to go to their food bowl and steal food from them. I do not think that they mind it much, but from what I can tell, she sees herself as being dominant to them. She apparently bosses them around sometimes, but I do not think that they are in danger of having their eyes pecked out.
Should I be allowing this?

It's tough to have a solo chicken. They are social animals. She probably thinks of the rabbits are really funny looking chickens, and she is probably acting in a dominant fashion. As long as she isn't harming the rabbits, I wouldn't change a thing. The hen is GORGEOUS because she hasn't had any other chickens to mess with her! If you put her by herself, I think she would be lonely. The rabbits are unlikely to be able to harm her unless they catch her off guard and give her a stout kick, but as long as everybody is playing nicely, my vote is to leave everything as it is now.
